When a user tells Hermine what clothes they need cleaned, the machine’s voice recognition system explains how they should be washed. Speech recognition software allows the machine to understand commands such as "prewash" or "wait 30 minutes before starting."
Speaking in a friendly woman’s voice, Hermine also gives advice on which washing detergent to use or how to remove tough stains. The Speech Experts team has tried to give the machine a personality. For instance, when told that a garment has been stained with red wine, Hermine responds by recommending beer in the future because those stains are easier to remove.
